he nervous system is the communication network of the body. It consists of a complex collection of nerves and specialized cells‚ called neurons‚ that transmit messages across the different parts of the body in order for it to function and react correctly. They are known as the building blocks of the nervous system. Structurally they have long extensions that extend out from the cell body. There are two types of these extensions; dendrites‚ which are extensions of the neurons that receive signals

The Nervous System is the system of cells‚ tissues‚ and organs that regulates the body’s responses to internal and external stimuli. In vertebrates it consists of the brain‚ spinal cord‚ nerves‚ ganglia‚ and parts of the receptor and effector organs. Your nervous system is composed of the central nervous system‚ the cranial nerves‚ and the peripheral nerves. The brain and spinal cord together form the central nervous system. The cranial nerves connect the brain to the head. The four groups of nerves

Communication Breakdown Deborah Tannen in her essay “Sex Lies and Conversation” points out the problems in communication between genders. She focuses on conversational styles and on how a person’s expectations of one’s reaction may cause misunderstanding. She emphasizes the importance of something she calls cross cultural communication. Tannen believes that in order to communicate properly with the opposite sex we must learn their culture and adapt to conversation with them. First‚ Tannen describes

Nervous System Functions of the Nervous System 1. Detect changes and feel sensations 2. Initiate responses to changes 3. Organize and store information Divisions 1. Central Nervous System – brain and spinal cord 2. Peripheral Nervous System – cranial nerves and spinal nerves (relays info to/from the CNS) - Autonomic Nervous System Nerve Tissue – neurons (nerve fibers) and specialized cells (Schwann‚ neuroglia) 1.

The Nervous System The nervous system is the most complex part of the body‚ as they govern our thoughts‚ feelings‚ and bodily functions. It is an important factor in science because it can lead to new discoveries for cures or diseases. The studies of the nervous system helped lower death rates from heart disease‚ stroke‚ accidents‚ etc. The nervous system is a network of neurons (nerve cells) that that sends information to the brain to be analyzed. Neurons live both in and outside the central nervous

CH 202 Breakdown UV/Vis: Molecules containing π-electrons or non-bonding electrons (n-electrons) can absorb the energy in the form of ultraviolet or visible light to excite these electrons to higher anti-bonding molecular orbitals. The more easily excited the electrons (i.e. lower energy gap between the HOMO and the LUMO)‚ the longer the wavelength of light it can absorb. Conjugation raises the energy of the bonding orbitals and lowers the energy of the antibonding molecular orbital. This

The nervous system consists of the brain‚ spinal cord‚ and a complex network of neurons. This system is responsible for sending‚ receiving‚ and interpreting information from all parts of the body. The nervous system monitors and coordinates internal organ function and responds to changes in the external environment. This system can be divided into two parts: the central nervous system and the peripheral nervous system. Let ’s take a look at the central nervous system. Central Nervous System The

The primary function of the meninges and of the cerebrospinal fluid is to protect the central nervous system. Layers of Meninges Dura Mater – means hard mother‚ the outermost w/c is tough & flexible. It surrounds & supports the large venous channels carrying blood from the brain toward the heart. Arachnoid membrane – the middle layer‚ so named because
